Function Usage

Creates a Const operator using an ABI-safe API.

Prototype

template <typename T> 
EsTensorHolder CreateConstV2(const std::vector<T> &value, const std::vector<int64_t> &dims, ge::DataType dt, ge::Format format = FORMAT_ND)

Parameters

Parameter	Input/Output	Description
value	Input	Tensor data vector.
dims	Input	Tensor dimension vector.
T	Input	Tensor data type.
dt	Input	Tensor data type.
format	Input	Tensor format. The default value is FORMAT_ND.

Returns

Parameter	Type	Description
-	EsTensorHolder	Tensor holder operator of the created Const. If the operation fails, an invalid EsTensorHolder is returned.

Restrictions

This API uses the CompliantNodeBuilder V2 API to construct a Const node, avoiding the risk of std::string transfer across the C++ ABIs in the old IR definition structure.

To use this API, the runtime software package must support CompliantNodeBuilder V2 symbols. To be compatible with old software packages that do not contain V2 symbols, use CreateConst.

Example

EsGraphBuilder builder("test_graph");
std::vector<float> vecf = {1.1, 2.0, 3.2, 4.4};
std::vector<int64_t> dims = {4};
auto c1 = builder.CreateConstV2<float>(vecf, dims, ge::DT_FLOAT);
